Inventor EKLQQQII/ the roper direction the cables can be wound on t e drums to raise the delivery end of the elevator', the latter being held automatically at the desired point of adjustment by means of a pawl Ll0, pivoted on one of the standards 7 and engaging the ratchet-wheel 41, sccured to the contiguous drum. (See Fig. 2.) By the proper curvature of slots Q the vertical adjustment of the delivery end of the elevator is accomplished without any longitudinal movement thereof, so that said elevator at whatever height from the ground it delivers shall always project thc same distance beyond the wheeled frame. 1n racticc the elevator will probably project lleyond the side of said frame about seven feet, so that it will build a stack about fourteen feet wide and always deliver in the plane of the longitudinal center of the stack, it being understood, of course, that as the delivery end is raised the angular relation of the elevator with respect to the ground varies, its receiving end approaching the wheeled frame as the delivery end rises and receding from said frame as the delivery end descends.

Secured rigidly to the elevator near its rcceiving end are standards 12, and journaled in said standards is a shaft 43, having a beltwheel -lf-l, connected by a cross-belt 45 to the pulley 3U, so that the rotation of the latter in the direction indicated by the arrow, Fig. 2, shall operate shaft 43 in the opposite direction, as indicated by the proximate arrow in said ligure. Pivoted on shaft 43 for movement in a vertical plane is a conveyor constructed as follows: lo indicates the sides, connected by the shaft 43 and by a shaft 47, the latter' being equipped with` a roller 48 and the former with sprocket-wheels 19. 5U indicates chains engaging the sprocket-wheels and roller 48, and 51 transverse slats Connecting the chains and provided with gathering teeth oir fingers 52, said shafts, sprockets, roller, chains, and toothed slats constituting an endless drag which in practice projects into the headerbox when the hinged side of the latter is lowered for the pur )ose of automatically dragging grain out ol said box and causing it to fall on the receiving end of the elevator. For the purpose of tending to swing the endless drag upward the standards 42 are equipped at their upper ends with guide-sheaves 53 and below the latter with vertical guide-rods 5a, engaged slidingly by weights 55, cables 56 engaging said sheaves, being attached at their opposite ends to said weights and to bolts 57, secured to the drag-frame. By means of these weights a constant lifting power is exerted on the drag-frame, which power has to be overcome by the operator, who stands in the header-box when the apparatus is unloading grain from the latter, and in order to insure the proper delivery of this grain onto the elevator a hopper is irovided, the back of the saine being formed by the depending side 2 of the header-box where the construction is such that said side depends as shown. The sides of the hopper are formed by the vertical boards 58, secured to standards 4Q, and the outwardly and downwardly converging wings 5E) united rigidly to boards 5S by'angle-irons (i0.

Then the grain is to he stacked, the slideframe is dis osed, by reference, at one end of the wheeler frame, t te hand-wheel 2l being manipulated to accomplish this purpose, as will be readily understood. The drums are manipulated to lower the elevator to about the position shown in full lines, and then thc drag-frame is swung in the direction indicated by the arrow r1 to the position illustrated in Fig. 2, where it will be noticed it is projected into the header-box, which it is supposed at this time is lillcd with grain, and is t isposed substantially parallel with the wheeled frame and opposite the same, so that when the elevator is near one end of the wheeled frame the drag shall be contiguous to the corresponding end olthe headerbox. An attendant stands in the header-box and presses the drag-frame down upon the grain as a second attendant or engineer starts starts the gas-engine or other motor in operation and simultaneously starts the dragframe and elevator in operation, the former dragging the grain out of thc header-box and disposing practically all of it, because of thc hopper described, upon the receiving end oll the elevator. The elevator discharges it at its opposite end upon the ground, ifa stack is to be lormcd,or into thc feeder ol' a threshingmachine (not shown) if the grain is to he iinmediately threshed. As the operation of the machine continues the opi-rator in the headerbox' gradually depresses the drag-frame, so that it shall descend as the volume of grain diminishes in depth or thickness. As the stack attains approximately the height of the delivery end of the elevator and the ends of the header-box where the drag is lowered is practically emptied the hand-wheel is turned to move the slide-frame about its own width, or the wheeled frame may be moved approximately said distance, (the former adjustment is preferred,) so that the drag will be disposed over an unemptied part of the header-box and the delivery end of the elevator will be disposed over the ground at a point to one side of the pile of grain already stacked, these adjustments or others by which the same object accomplished being repeated at intervals until a stack has been built which corresponds in length with the wheeled frame and in height with the distance between the ground and the delivery end of the elevator, it being understood, of course, that in this operation. the contents of several header-boxes may have been unloaded. After the stack has grown to about the proportions stated the :crank -handle 39 is manipu- IXO
